Transportable Roadworks Traffic Signal Systems

Transportable Roadworks Traffic Signal System Type MPB 3400

The latest radio transmission technology gives the MPB 3400 a reliable digital radio path with high-quality transmission. The multi-frequency version of the traf c light can be supplied with up to 16 radio channels on request.

tested as per TL-LSA 97 for alternating one-way traffic, T-junctions and crossroads control (to comply with the TL-LSA, traffic lights in Germany have to be wired for crossing traffic ows).

clearly arranged controls: all at a glance.

standard halogen lamps or innovative LED technology with night-time reduction feature on request.

all signal heads identical: can be extended immediately by simply adding more signal heads to obtain T-junction or crossroads control – also by radio.

in contrast to competing suppliers, a crossroads traffic light consists of four identical full traffic lights that can be combined at random, instead of one transmitter and three receivers.

vehicle-actuated control with directional radar detectors.

different modes can also be mixed, for example: main road with green phase extension and side road (or roadworks exit) on request.

Innovative technology with simple operation at a glance.

Applications:

The mobile traffic-light system MPB 3400 can be used either with radio, cable or quartz control. The standard version is designed for controlling bottleneck situations (with extension also for T-junctions* or crossroads*). The VA version of the MPB 3400 has directional radar detectors as a standard feature to warrant reliable vehicle-actuated operation. The MPB 3400 is quickly installed and is easy to operate intuitively without any special previous knowledge.

The clearly arranged controls for MPB 3400 are extremely easy to operate, and can be clearly read even when switched off. Radio, cable or quartz control is chosen with the function switch.

The mode switch then selects the required setting. Fixed-phase, request and green phase extension mode can be chosen separately for every traf c light and even mixed in combination.

All signal heads are identical so that the user decides which signal heads will function as transmitter and which as receiver with active feedback.

The necessary clearance times (interim times) and the green phases are adjusted with the knob on the transmitter and receiver controller. These times can also be adjusted separately in each direction for radio or cable operation.

The illuminated info display even provides information about the other side in radio or cable mode. As a result, it is possible e.g. to read off the signal and cycle status or see a pending fault (e.g. battery warning) in manual mode at every signal head.

Technical data

Operation voltage

approx. 8-14V DC (electronic reverse polarity protection as well as under- and over-voltage protection; no loss of data when changing the battery)

* In the export version, T-junctions or crossroads can also be controlled with the digital radio path. Automatic changeover between radio and quartz operation in bottleneck situations can be activated on request.

Mobile traffic-light system type MPB 3400 – for universal use with radio, cable and quartz control.

The clearly arranged controls for MPB 3400 are extremely easy to operate, and can be clearly read even when switched off.
